Dramatic dried-up river channels over a mile wide and 650 feet deep have been detected on Mars, showcasing how the Red Planet once hosted liquid water at its surface.
A species of large tortoise not seen since 1906 has been rediscovered on a remote part of the Galápagos Islands, kindling efforts to conserve the critically endangered animal.
Introducing Hippocamp—the smallest of Neptune’s seven inner moons. The recently discovered moon likely formed from a collision with another moon billions of years ago.
Instruments aboard NASA’s InSight lander are now gathering meteorological data from the Martian surface, allowing for daily weather reports that are being made available to the public.
Earlier today, President Donald Trump signed a directive to create the Space Force, what will become the sixth branch of the U.S. military—but the new branch will be placed under the purview of the U.S. Air Force, rather than being a separate and autonomous branch, as the president had initially hoped.
An 80-year-old woman from the United Kingdom is the first patient to undergo gene therapy to treat age-related macular degeneration—the most common cause of sight loss in the world.
A small satellite has captured a piece of space debris using a claw-tipped harpoon. The test represents an important technological achievement given our mounting space junk problem.
NASA has officially called an end to the historic Opportunity rover mission, ending a spectacular, 14-year adventure on the Red Planet. One of the rover’s most intriguing discoveries, however, came just two months after it landed, when it stumbled upon tiny objects bearing a startling resemblance to blueberries—the…
A newly approved NASA mission, called SPHEREx, will use a space-based observatory to study the early conditions of the Universe and hunt for the celestial ingredients required for life.
Tepco, the state-owned operator of the badly damaged Fukushima nuclear plant, has conducted an important test in which a remote-controlled probe managed to grasp several small grains of radioactive debris, AFP reports. The successful operation marked an important achievement for the company as it prepares for a clean…
Titanosaurs were the giants of the giants—four-legged behemoths that stomped around Cretaceous South America and Africa 100 million years ago. The discovery of a previously unknown titanosaur in Tanzania with a unique heart-shaped tailbone is adding to our knowledge of these enigmatic beasts, and how they lived and…
After 77 years, the wreck of the USS Hornet has finally been found, lying more than three miles deep in South Pacific waters. The storied aircraft carrier—sunk by Japanese torpedoes in 1942 with the loss of 140 men— played a critical role during the Second World War, most famously in the Doolittle Raid and the Battle…
The reported discovery of 2.1-billion-year-old fossilized track marks etched in sedimentary rock is pushing back the earliest evidence of self-propelled movement by an organism on Earth by a whopping 1.5 billion years.
The twisting terrain of Vera Rubin Ridge on Mars has been home to NASA’s Curiosity for over a year, but it’s time for the rover to move on. As a final gesture before trekking toward a nearby region rich in clay, the probe captured a stunning 360-degree panorama of its final worksite at the ridge.
When plumbing planner Jannick Vestergaard and engineer Henning Nøh woke up on the morning of February 5th, it likely never occurred to them that their day’s work would result in the discovery of an extraordinary double-edged sword dating back to the 14th century.
The appearance of a massive white cap on Uranus may seem alarming, but as planetary scientists are learning, this is what a prolonged summer looks like on the remote ice giant.
A 52-million-year-old fossil found in Wyoming is now the earliest known seed-eating perching bird in the scientific record, a discovery that’s shedding new light on the history and early eating habits of these now-ubiquitous birds.
Three high-profile faculty members at Stanford University are under investigation for alleged ties to He Jiankui, the Chinese scientist who claimed to use CRISPR to produce genetically modified human babies last year, MIT Technology Review reports.
An image captured by NASA’s Lunar Reconnaissance Orbiter shows the Chang’e 4 landing site from a distance of over 200 miles, revealing both the probe and the desolate lunar landscape around it.
A new study suggests honeybees inherently understand the rudiments of addition and subtraction, a finding that highlights the remarkable cognitive abilities among even the tiniest of creatures. Critics, on the other hand, say the new research proves nothing of the sort.
